Legacy Electrical and Cable Specifications

The following electrical documentation is for legacy products, JS-20SR, JS-20XR, JS-20WA, and JS-20DL.

Input Specifications

The encoder output should be either 5V DC push-pull, or an open-collector. A differential output (e.g. RS-422) can be converted by using a Crouzet relay (part no. 84130104) or a differential to push-pull converter.

The Start Scan input signal is by default active low — low voltage causes the scanners to start synchronized scanning. However, the StartScanTriggerOnHigh parameter reverses this, and causes the scanners to start synchronized scanning when the Start Scan input is high voltage.

12-Wire Pinout

JS-20 scanners are generally connected with our standard 12 wire cable. Belden 9457 or an equivalent cable is suggested.

Sample Wiring Schematic

This is a sample wiring diagram that shows how to wire up three JS-20 scanners with separate cable IDs. Note how the unused Address wires are simply left unconnected.

15-Wire Pinout

In some applications you may want a signal of when the lasers are on. For these applications, we supply a 15-wire cable with a Laser On output, which is pulled low when the laser is on. Belden 8458 or an equivalent cable is suggested.

This is an extremely uncommon type of wire for the JS-20s.

Cable ID Wiring

The A0 through A4 wires are used to give each cable a unique Cable ID number. Instead of having to manually configure a scanner's location, a JS-20 simply configures itself according to the Cable ID that supplies power to the scanner. To set a Cable ID, pull specific Cable ID wires A0 through A4 to the isolated ground. The remaining wires should be left unconnected. The table below gives the wiring for all 32 possible addresses.

U = Unconnected

G = Grounded
